This is a notion that has been explored before in such excellent films as the aforementioned “Brazil” and the even-more-underrated “Pennies from Heaven,” that strange and sadly beautiful Dennis Potter creation in which a Depression-era sheet music salesman sees himself as the hero of a series of elaborately produced musical numbers when the pressures and disappointments of real life became too much.
Perhaps meaning can no longer be generated except by slamming together familiar signifiers in new way, which is why one single film can crib so freely from Brazil , One Flew Over the Cuckoo's Nest , Crouching Tiger, Hidden Dragon , Blade Runner , Moulin Rouge! , the collected works of David Carradine, the Star Wars franchise, and a hell of a lot of more elemental generic tropes from horror, sci-fi, jidaigeki, sword & sorcery fantasy, and video games galore - the most staggeringly obvious of which is Wolfenstein 3D though the last sequence, on a train, reminded me of a level in Star Wars: Shadows of the Empire to a degree that I'd have thought impossible for a game I haven't played in over a decade.
